[ubuntu] TTY resolution problem

view story

http://ubuntuforums.org – Hi all, Recently I've found that my TTY (when pressing alt-ctrl-fn) not displaying properly. I'm not sure if this has to do with my recent upgrade of nvidia graphic driver (nvdia-current in the default repository) from the open source driver (to solve suspend problem). I'm using Ubuntu 13.04 The TTYs just display in a manner that the text is disproportioned and not using the whole screen (so only the middle 70% portion of the screen is used). I've tried various methods found on the web: - alter /etc/default/grub - alter /etc/grub.d/00_header - grphical method: grub customiser but none of them (Hardware)
